I was reading through the manual and noticed the procedure to change spark plugs. It says you have to remove the speedometer and gas tank!?! Guess I didn't see that coming. How difficult is it? Also, for storage, it says to change the oil before storage and then change it again before taking it out of storage. Seems to me the first oil would be fine if it's just sitting in the engine unused. Does everybody else out there follow this procedure by the book?
